Electric circuits — practice question

Three resistors with resistances $1.0\,\Omega$, $2.0\,\Omega$ and $3.0\,\Omega$ are joined in parallel across the terminals of a cell. Which statement is correct?

  • AThe currents in the resistors are equal.
  • BThe sum of the currents in the three resistors is equal to the current in the cell.
  • CThe sum of the potential differences (p.d.s) across the resistors is equal to the electromotive force (e.m.f.) of the cell.
  • DThe potential difference across the $3.0\,\Omega$ resistor is greater than the potential difference across the other two resistors.
